Rare earth elements extracting process. Rare earth elements are far more complicated and costly to extract. (See Diagram 1 below) First, ore containing minerals (for this example, we will look at bastnaesite), is taken out of the ground using normal mining procedures. The bastnaesite must then be removed from the ore, which generally contains a number of other minerals of little value. The ...

Flotation at a pulp temperature of 40 deg to 45 deg c yielded a cleaner concentrate containing pct re2o3 at a rareearth recovery of 67 pct. These results are comparable to those reported for the commercial beneficiation method in which the pulp is heated to boiling before flotation. An attempt was also made to recover a barite flotation concentrate from the bastnasite rougher tailing ...
